Fitbit Lifespan: Understanding Battery and Device Longevity

Table of Contents

Fitbit is a popular brand of fitness trackers that has become increasingly popular over the years. One of the most common questions among users is how long does a Fitbit last? The answer to this question is not straightforward as it depends on several factors.

On average, a Fitbit will last between one and two years if it is kept in excellent shape. However, with normal use, they last about 16-18 months. The lifespan of a Fitbit depends on various factors such as the quality of the hardware, water resistance, frequency of cleaning, battery health, reset frequency, and the Fitbit model you buy.

Many factors can affect the lifespan of a Fitbit, but taking good care of your device will undoubtedly extend its life. In this article, we will discuss the factors that affect the lifespan of a Fitbit and provide tips on how to extend the life of your Fitbit.

How Often Do Fitbits Need To Be Replaced?

Fitbits are designed to last for a certain period of time, but how long that period is depends on several factors. The frequency of replacement can vary depending on the model of the Fitbit, how often it is used, and how well it is taken care of.

On average, a Fitbit will last between one and two years if it is kept in excellent shape. But with normal use, they last about 16-18 months. The quality of the Fitbit’s hardware, water resistance, frequency of cleaning, battery health, reset frequency, and which Fitbit model you buy can all affect how long it lasts.

If you notice that your Fitbit is not working properly, the first thing you should do is try to troubleshoot the issue. This may involve resetting the device, cleaning it, or checking the battery. If the problem persists, you may need to replace it.

It’s important to note that Fitbit offers a one-year limited warranty on its products, which covers defects in materials and workmanship. If your Fitbit is still under warranty and you are experiencing issues, you may be able to get a replacement for free. However, if your Fitbit is out of warranty or the issue is not covered by the warranty, you will need to purchase a new one.

What Are The Factors That Influence A Fitbit’s Longevity?

A Fitbit’s lifespan can be affected by various factors. Here are some of the most important ones:

  • Hardware Quality: The quality of the hardware is a critical factor in determining how long a Fitbit lasts. Higher quality hardware can last longer and be more durable.
  • Water Resistance: Water resistance is another essential factor in determining a Fitbit’s longevity. If a Fitbit is exposed to water frequently or for long periods, it can lead to corrosion and damage to the device.
  • Battery Health: The battery life of a Fitbit can degrade over time, which can affect the device’s overall lifespan. If the battery is not replaced or maintained, it can cause the Fitbit to stop working.
  • Frequency of Resets: Resetting a Fitbit frequently can cause wear and tear on the device, which can shorten its lifespan. It is essential to avoid resetting the device unless necessary.
  • Frequency of Cleaning: Cleaning a Fitbit regularly can help keep it in good condition and prolong its lifespan. Dirt, sweat, and other debris can accumulate on the device and cause damage if not cleaned properly.

These are just a few of the factors that can influence a Fitbit’s longevity. It is essential to take care of your device properly to ensure that it lasts as long as possible.

Fitbit Battery Life Expectancy

One of the most important features of a Fitbit is its battery life. Users want to know how long they can expect their device to last before needing a recharge or replacement. In this section, we’ll explore the average battery life of Fitbit models and the factors that affect their battery life expectancy.

Average Battery Life of Fitbit Models

The battery life of a Fitbit varies depending on the model and usage. On average, a fully charged Fitbit battery can last between five and seven days. However, some models like the Fitbit Ionic and Fitbit Versa 2 can last up to 10 days on a single charge. On the other hand, the Fitbit Charge 4 and Fitbit Inspire 2 typically last around five days.

It’s important to note that battery life can be affected by how often you use your device and which features you use. For example, using the GPS feature on a Fitbit can significantly reduce its battery life.

Factors Affecting Fitbit Battery Life

Fitbits are designed to last for a certain amount of time before needing to be recharged. However, several factors can affect the battery life of your Fitbit. Understanding these factors can help you maximize the lifespan of your device.

Usage Frequency

The frequency of usage is one of the most significant factors that affect the battery life of your Fitbit. The more you use your device, the faster it will drain the battery. If you use your Fitbit for tracking your sleep, exercise, and other activities, it will drain the battery faster than if you only use it for basic tracking.

Display Settings

The display settings of your Fitbit can also impact its battery life. If you set the screen brightness to a high level, it will consume more battery power. To conserve battery life, try setting the brightness to a lower level or using the auto-brightness feature.


If you have enabled notifications on your Fitbit, it will also consume more battery power. Every time you receive a notification, your device will vibrate and display the message on the screen, which will drain the battery. To extend the battery life, consider disabling notifications or reducing the number of apps that send notifications to your Fitbit.

GPS and Heart Rate Monitor

The GPS and heart rate monitor features on your Fitbit can also drain the battery quickly. If you frequently use these features, it will reduce the battery life of your device. To conserve battery life, try turning off these features when you don’t need them.

Battery Age

The age of your Fitbit’s battery can also affect its lifespan. Over time, the battery’s capacity will degrade, which means it will hold less charge than when it was new. If you notice that your Fitbit’s battery life is significantly shorter than before, it may be time to replace the battery.

Tips to Extend Fitbit Battery Life

Charging Practices

One of the best ways to extend your Fitbit’s battery life is by following proper charging practices. Here are some tips:

  • Charge your Fitbit when it’s low on battery, but not completely dead.
  • Use the Fitbit charging cable that came with your device. Third-party cables may not work as well and could damage your Fitbit.
  • Charge your Fitbit in a cool, dry place. Avoid charging it in direct sunlight or in hot environments.
  • Don’t leave your Fitbit charging for more than a few hours after it’s fully charged. Overcharging can damage the battery.

Disabling Unused Features

Another way to extend your Fitbit’s battery life is by disabling features that you don’t use. Here are some features that you can disable:

  • All-Day Sync: This feature syncs your Fitbit with your phone or computer throughout the day. Disabling it can save up to 24 hours of battery life.
  • Heart Rate Monitoring: If you don’t use your Fitbit to track your heart rate, you can turn off this feature to save battery life.
  • Notifications: If you don’t need to receive notifications on your Fitbit, turn off this feature to save battery life.

Using Power-Saving Modes

Fitbit devices come with power-saving modes that can help extend battery life. Here are some power-saving modes that you can use:

  • Quick View: This mode turns off the display after a few seconds of inactivity. To wake up the display, you need to tap your Fitbit.
  • Screen Wake: This mode turns off the display until you press the button or lift your wrist to wake it up.
  • Ambient Light Sensor: This mode adjusts the brightness of the display based on the ambient light in your environment.

Using Third-Party Apps

Using third-party apps on your Fitbit can drain your battery faster. Here are some tips:

  • Only install apps that you need.
  • Check the battery usage of each app in the Fitbit app settings. If an app is using too much battery, consider uninstalling it.
  • Don’t use apps that require a constant connection to your phone or computer.
